The Ashley reports that Houska, who is expecting a baby girl, refused to go to the set on Sunday because she was “very upset” about Lowry and DeJesus’ physical altercation on the set on Saturday, May 19.

The website reports that Houska and her crew left the studio after the brawl and didn’t return. Producers “tried to convince Chelsea to come on Sunday, but she still refused,” a source told The Ashley, which reports that the expectant mom of two had been promised that precautions were being taken to ensure no fights would break out and that she would be safe.
